[SR-Users] 420 Bad Extension error

Thu Oct 13 09:51:58 CEST 2016

Hi Daniel,

I find only this error message in syslog. Rest are normal.

Oct 13 07:41:15 infinicalls /usr/local/sbin/kamailio[32948]: ERROR:
<script>: t_(load|next)_contacts() failed

Oct 13 07:41:15 infinicalls /usr/local/sbin/kamailio[32948]: ERROR: sl
[sl_funcs.c:363]: sl_reply_error(): ERROR: sl_reply_error used: I'm
terribly sorry, server error occurred (1/SL)

I am not sure, if this is the correct one. Kindly guide me.

And is this related to this
https://github.com/kamailio/kamailio/issues/497 ? If yes, I think I
need to update to the latest version of Kamailio.

regards
Ganesh Kumar
